Cover Crops in Brunei | Chemiseed Supply
Chemiseed supplies leguminous cover crop seeds and SoilBoost EA soil conditioner to plantation projects and smallholder programs in Brunei Darussalam. Cover crops fix nitrogen, hold soil during the immature phase of tree crops, suppress weeds, conserve moisture, and build organic matter on tropical soils.
At a glance: Brunei context
- Agriculture diversification: Brunei's Ministry of Primary Resources and Tourism has prioritised agriculture and agri-food as part of the Wawasan 2035 diversification agenda, with land allocations for plantation trials and food crops.
- Oil palm trial blocks: Limited oil palm plantings have been established at trial scale on government-allocated land, supported by Brunei's agriculture programs.
- Smallholder food crops: Rice, fruit, and vegetable programs are supported under Brunei's food security initiatives, with soil structure on humid tropical soils a recurring concern.
- Common challenges: high rainfall, leached tropical soils, and the need for fast early ground cover at establishment.
Cover crop species relevant to Brunei
Pueraria javanica (PJ): vigorous core legume
PJ (tropical kudzu) is well suited to Brunei's humid tropical climate and is the standard core legume in regional oil palm and rubber systems. Seeding rate: 4 to 6 kg/ha. PJ typically contributes on the order of 40 to 70 kg N per hectare in plantation systems, depending on age and establishment.
Calopogonium mucunoides (CM): fast pioneer
CM establishes quickly in the first months after planting and is widely used as a pioneer in tropical plantation systems near the equator. Seeding rate: 4 to 6 kg/ha as a mono stand.
Mucuna bracteata (MB): nursery-raised, long-lived cover
MB produces dense, persistent ground cover suitable for oil palm and rubber blocks. It is nursery-raised and transplanted at about 320 seedlings per hectare (roughly 85 to 100 g of seed per hectare). It is not broadcast like the other species.
Centrosema pubescens (CP) and Calopogonium caeruleum (CC): shade tolerant
As the tree canopy closes, shade-tolerant legumes carry the cover forward. CP seeding rate: 3 to 4.5 kg/ha. CC seeding rate: 3 to 4.5 kg/ha.
SoilBoost EA on humid tropical soils
SoilBoost EA is a Leonardite-derived humic acid soil conditioner manufactured exclusively by Chemiseed Sdn. Bhd. in Malaysia. It is 60.6% humic acid by the CDFA method, pH 3.84, with 0.45% sulfur. On humid, leaching-prone soils typical of Borneo, a humic acid conditioner supports soil condition and structure. SoilBoost EA is applied by broadcast at 50 to 100 kg/ha or by drench at 10 to 15 kg/ha. It is a soil conditioner: it is not a fertiliser substitute and not a disease treatment.
